nix: remove explosions if you have a window size less than four

Turns out strings do not like being resized to -4.

This was discovered while messing with the tests to remove unbuffer and
trying stdbuf instead. Turns out that was not the right approach.

This basically rewrites the handling of this case to be much more
correct, and fixes a bug where with small window sizes where it would
ALSO truncate the attr names in addition to the optional descriptions.
